I ordered 12mm x 1.25 stop lugs as shown in the product description. Unfortunately I was not able to inspect the ears prior to installation. Turns out I was sent 12mm x 1.5 locking lugs which damaged a stud on each of my wheels. I can't return them as the wheel shop lost one of the two keys and the packaging was thrown away. To top it off I had to pay $162 to replace the bolts and now I don't have a locking eyelet to fix it. my new wheels :( The price I paid for the replacement bolts was a bargain as the local dealers wanted over $460 at current labor prices in my area. Although I like the finish of the product and the matching normal non-locking Loved the cleats It was a BAD buy because it cost me the price of that part plus extra money for repairs and a big headache.
